When it comes to sewage filtration equipment, many people sometimes can not tell the self-cleaning filter andSecurity filterThese two kinds of equipment, in order to let everyone on the two devices between the various differences have a more in-depth understanding, small part of the purpose of sorting out the differences between the two devices, to solve everyone's doubts.

1, the product shape is different
2, the principle of filtration is different:
Self-cleaning filter principle: Self-cleaning filter generally selected is carbon steel or stainless steel as a shell, the primary filter to block impurities, its primary role is to remove particulate matter in the water, suspended matter, etc., arrived at the intention of purifying water quality. General self-cleaning filter is the sewage into the inlet, first through the coarse filter filter off the impurities of larger particles, and then reach the fine filter. In the filtration process, the fine filter gradually accumulates the dirt and impurities in the water, forming the filter impurity layer, because the impurity layer accumulates on the inside of the fine filter, the inner and outer sides of the fine filter constitute a pressure difference. When the pressure difference of the device reaches the preset value, the initial automatic cleaning process.
Security Filter Principle: Security Filter (also known as fine filter) mostly choose stainless steel shell, internal filter filter (such as PP Cotton), Security filter selection Molding filter material, under the action of pressure, so that the original liquid through the filter material, filter slag left on the pipe wall, filter through the filtration material outflow, and then arrive at the intention of filtration. First used in multi-media pretreatment filtration, reverse osmosis, ultrafiltration and other membrane filtration equipment before. Used to filter out fine substances (such as fine quartz sand, activated carbon particles, etc.) after multi-media filtration to ensure that water quality filtration accuracy and protective film filtration elements are not damaged by large particulate matter.

3, the filter media is different:
It can be seen in the picture at the beginning of the article. Self-cleaning filter inside the selection of stainless steel filter for filtration, security filter inside the selection is the device filter filter, the general material is PP cotton, nylon, melt spray and so on.
4, anti-scour effect is different:
Self-cleaning filter can automatically reverse scour, the general reverse wash time can be set, the moment is short, the moment 10 seconds or so. The security filter, on the other hand, cannot be backwash.
These are some of the differences between the security filter and the self-cleaning filter. It is expected that this article will help you learn more about the differences between the two devices.
